Tear gas is a very good place to start trying to understand what is happening in Turkey. The main purpose of tear gas is to terrorise and thus break up large crowds of people. In Istanbul over the last weeks huge quantities have been used over and over to prevent large anti-government demonstrations developing.

This wasn't about 'riot control' - generally there was no riot to control.
